Hello Gurus
10:1 Capacitive-input probes has a 10Mohm series resistance at probe tip. What
is the purpose of the resistor?
The answers that I have in my mind are:1) to be able to measure high DC
voltage2) so that the input capacitive loading is small3) to minimize the
loading that the cable capacitance would impose on the DUT
Am I right about?
RegardsYing
